Subject: Christine Bernardi

Our colleague Christine Bernardi died suddenly on the night of March
10, 2018. Director of research at CNRS within the Laboratoire
Jacques-Louis Lions where she had spent her entire career, since her
thesis with Pierre- Arnaud Raviart. She retired for health reasons a
year ago.

She collaborated with an incredible number of people; she was
recognized and appreciated worldwide for her seminal research on the
numerical analysis of partial differential equations.

We will always remember a colleague who was always available and very
involved in the life of the community. She carried out numerous
international initiatives, notably with Italy and the Maghreb (see
Christine's website). Her daily involvement, her scientific
initiatives and her constant good spirits have punctuated our daily
lives for over 35 years.

Her family has created a web page where you can leave a souvenir

Subject: Joseph Flaherty (1943-2018)

Dr. Joseph Flaherty passed away on March 28, 2018.  Joe studied at the
Polytechnic Institute of Brooklyn, where he earned degrees in
aerospace engineering and applied mechanics.  In 1972, he joined the
faculty at Rensselaer Polytechnic Institute where he remained until
his retirement in 2005. He was instrumental in the establishment of
RPI's Department of Computer Science and was its chairperson for seven
years.  He achieved the rank of Amos Eaton Professor, an honor named
for the co-founder of RPI.  He also served as the Dean of RPI's School
of Science.  Joe's research focused on numerical analysis, adaptive
finite element methods, and high-performance computing.  During his
tenure, he co-authored thirteen reference books, wrote countless
journal articles and papers, spoke at conferences around the world,
and served as a thesis advisor and mentor to numerous students and
doctoral candidates.  He was a member of eight professional societies
and four honor societies.  Memorial services will be held April 21,
9:30am, at The Chapel + Cultural Center at Rensselaer Polytechnic

Subject: 2018 Atrial Segmentation Challenge

Segmentation of the 3D atrial chambers from MRIs provides vital
information for patient specific diagnostics and treatment.  Nowadays,
gadolinium-based contrast agents are used in a third of all MRI scans
(GE-MRI) to improve the clarity of the images of a patient's internal
structures including the heart, by improving the visibility of often
disease associated structures, such as fibrosis.

Direct segmentation of the atrial chambers from GE-MRIs is very
challenging due to the attenuation of the contrast between normal
myocytes of the atrial tissue and background. Most existing structural
analysis studies, especially those that utilize GE-MRIs, have been
based on labour intensive, error/bias prone approaches.  Hence, there
is a need for an intelligent algorithm that can perform fully
automatic atrial segmentation, particularly in the left atrium, to
accurately reconstruct and visualise its geometry for clinical usage.

The 2018 atrial segmentation challenge will provide the largest
dataset of such kind to participants: A total of 154 3D GE-MRIs for
training and testing. This challenge, in conjunction with 2018 STACOM
workshop and MICCAI conference (16-20 September 2018 in Granada,
Spain), will provide an open competition for wider communities to test
and validate their methods on image segmentation and further push the
state-of-the-art performance.

The atrial segmentation challenge will start on 4 April, 2018. For
detailed information including image data and prizes, please check the

Subject: Applied Mathematics and Computational Science, Cuba, Jun 2018

The IX PanAmerican Workshop in applied mathematics and computational
science will be held in Varadero, Cuba June 11-18 2018 The objective
of these workshops is to create cooperative research activities based
on international collaboration and to promote the development of
applied and computational mathematics in Latin America.  To accomplish
these goals, we must bring together practicing applied mathematicians
and computational scientists in the Americas to exchange research
information, and create a forum for researchers to refine, enhance and
implement research activities. The purpose is to continue to center in
areas of applied and computational mathematics, such as, computational
fluid dynamics, numerical optimization, high-performance computing,
grid generation, computer algebra, and dynamical systems aimed to
evaluate data related to areas of environmental, social and economic
development in the
